After previously calling it quits, Bobbi Kristina and Nick Gordon are once again engaged, and this time it's OFFICIAL!

Whitney Houston's daughter made the exciting announcement on Facebook, but instead of focusing on the joyous occasion, she spent most of the time stressing one very important detail. That Nick is NOT her biological brother!

Shane Redway -- a Canadian rapper and close friend of Drake's -- was killed early Saturday morning in a car crash. He was just 26 years old.

Redway and two others were killed when their car lost control, struck a guardrail and burst into flames. The crash occurred around 4am outside Pearson International Airport in Toronto. It's unclear who was behind the wheel. Police are investigating the crash.

Drake took to Instagram to remember Redway, posting two different tributes.
